The drug that reverses the effects of a heroin overdose will be available without prescription to the general public.

New York State Health Commissioner Doctor Howard Zucker says Naloxone, otherwise known as Narcan is going to be available at 479 CVS pharmacies across the state.

The reversal drug is being widely used by police, emergency services and ambulance crews in the region.

The health department says Narcan can’t be abused on its own since it only works when there is an opioid in a person’s system.

Once administered, the patient should be taken to the hospital before the Naloxone effects wear off.
